    BME280 resetting by cycling VDD, voltage requirement?

    Dear Bosch,

    For your sensor, BME280, according to the datasheet, it is possible to reset the BME280 by cycling the VDD voltage (page 12, section 5.2).

    What voltage will guarantied initiate a reset. If for example the VDD supply voltage is 3.3V, will lowering it to 1.2V and then raising it again to 3.3V initiate a reset?

    For how long time must the voltage be below the threshold?

    Best regards,

    Rune Jacobsen

    The BME280 is expected to trigger a POR if VDD is kept below 1.5V for at least 2ms.
